A number of users have reported problems using the Touch ID fingerprint scanner in the iPhone 5s, and Macworld’s Serenity Caldwell offers some tips on reducing frustration. In particular, she advises scanning your fingerprint at the same angle that you’d most likely use to unlock the iPhone, and if that’s not enough, adding multiple scans at different angles. She also explains some situations where Touch ID might not work well, if at all. follow link
Copy Before Submitting Web Forms
Filling in Web forms (like the one used to submit this tip) can be a bit of a gamble - you put in your pearls of wisdom, perhaps only to lose them all if the Web page flakes out or the browser crashes. Instead of losing all your text, "save" it by pressing Command-A to select all and then Command-C to copy the selected text to the clipboard. Do this periodically as you type and before you click Submit, and you may "save" yourself from a lot of frustration. It takes just a second to do, and the first time you need to rely on it to paste back in lost text, you'll feel smart.
